摘要：Cross-laminated timber (CLT), a high-performance engineered wood product, is used as an infill wall embedded in a steel frame using standard bracket connections, forming a hybrid lateral resistance system. This paper investigated the hysteretic behavior study of bracket connections in hybrid steel-cross laminated timber(CLT) wall. The performance of four types of bracket connections on beams and columns were tested under general quasi-static monotonic and cyclic loading protocols. The Pivot model was then used to quantify the hysteretic behavior of the connections in SAP2000 software. Based on the calibrated bracket connections, a numerical model of the hybrid steel-CLT wall was developed to predict the lateral performance of the hybrid wall under cyclic loading. The results were then compared to previous experimental results from a one-half-scale hybrid steel-timber shear wall. The failure mechanics of bracket connections at different locations in a hybrid steel-- cross laminated timber(CLT) wall were discussed and analyzed. The results revealed that the Pivot model can accurately captures the nonlinear behavior, strength degradation, stiffness degradation, and pinching effects of the bracket connections. Numerical simulations of the hybrid steel-CLT wall based on the Pivot model were in good agreement with the experimental results. The results revealed that bracket connections effectively coordinate the relative deformation between the steel frame and the CLT panel. Notably, in the hybrid steel-timber shear wall system, significant tension and shear damage occurred at the corner connections during quasi-static testing.
